The aim of this article is to emphasize and focus on the preclinical and clinical update on phytochemicals and their role in prevention of oral carcinogenesis. Accordingly, the literature search was made following database: Embase, Medline, Science Citation index, NIH public access, pubmed and Cochrane Database of systematic reviews. Several internet websites were also searched to access publications from major phytochemical research sites and relevant information was obtained with regards to each plant chemical. The authors also spotted different list servers through, Stanford cancer research etc: The data base search was made from the inception to 1988 and updated till 2013. A systematic method was obtained for literature search and data collection was critiqued. 60 articles were searched, among which there were only 6 systematic reviews on phytochemicals regarding oral carcinogenesis. Additional articles were obtained on phytochemicals and their mechanism of action in other cancers, which were regarded as background material. The studies done by various authors on each phytochemical has been briefly emphasized. © 2014 The Authors.

Biomaterial science is an expanding area, which encompasses a wide range of medical knowledge involving arthroplasty, cochlear implants, heart valves designing, lenses, dental fixation and tissue engineering. Within this context, in vitro cell culture on polymer scaffolds is one of the adopted strategies for tissue creation. It consists of a specific cell line that is seeded onto a particular substrate. This scaffold should provide excellent biocompatibility, controllable biodegradability, appropriate mechanical strength, flexibility as well as the ability to absorb body fluids for delivery of nutrients. Collagen certainly fulfils these demands; therefore, it is often chosen as a biomaterial. Moreover, this protein is abundant in the animal kingdom and plays a vital role in biological functions, such as tissue formation, cell attachment and proliferation.

Teeth are the most natural, noninvasive source of stem cells. Dental stem cells, which are easy, convenient, and affordable to collect, hold promise for a range of very potential therapeutic applications. We have reviewed the ever-growing literature on dental stem cells archived in Medline using the following key words: Regenerative dentistry, dental stem cells, dental stem cells banking, and stem cells from human exfoliated deciduous teeth. Relevant articles covering topics related to dental stem cells were shortlisted and the facts are compiled. The objective of this review article is to discuss the history of stem cells, different stem cells relevant for dentistry, their isolation approaches, collection, and preservation of dental stem cells along with the current status of dental and medical applications.

Objective: The relationship of the first deciduous tooth eruption and the general health of an infant has always been a subject of curiosity. The enigma of teething although historical, continues to pervade contemporary child health care due to many unexplained teething myths. The treatment modalities used in teething have been diverse. The objective of this study was to evaluate the awareness, beliefs and knowledge of parents towards teething symptoms. Materials and method: Hundred parents were randomly selected from two kindergarten schools and were interviewed according to a structured questionnaire. Collected data was analyzed by a statistical software known as SPSS. Results: Results revealed that though parents knew about teething but there was lack of awareness regarding diverse treatment modalities and the teething myths and realities. Conclusions: More educative programs should be initiated to make parents aware of teething myths and realities.

Prevention and treatment of oral diseases and diabetes require persistent daily self-care, as there is a mutual association between periodontitis severity and level of diabetes control. In this questionnaire study, we investigated oral health behavior, attitudes, and knowledge of diabetes-related factors among 500 Indian adults with type 2 diabetes mellitus. The questionnaire asked about oral self-care, dental visits, self-perceived problems, and knowledge of the relationship between diabetes and oral health. The most recent glycosylated hemoglobin (HbA1c) value was obtained from patient medical records. Overall, 22% of participants reported twice-daily toothbrushing; women were more likely than men to brush twice daily (P< 0.001). With respect to age and diabetes control, participants aged 35-44 years with good diabetes control had the highest rate of twice-daily brushing (P< 0.001). Oral self-care and use of dental services were poor among participants. The present results indicate that Indians with type 2 diabetes need further promotion of oral self-care and regular dental checkups to compensate for their increased risk of oral disease.

Osteoporosis is one of the most common human bone diseases affecting millions of people, including over one-third of females above the age of 65. Osteoporosis is characterized by decreased bone density and weakened bones. There is evidence that osteoporosis affects the craniofacial and oral structures, although the contribution of osteoporosis in the loss of periodontal attachments, teeth, and height of the residual ridge has not been clearly elucidated. Therefore, the relationship between systemic osteoporosis and oral health is still a complex problem of great interest to a large number of researchers and clinicians. In addition, the dentist could screen patients with unrecognized osteoporosis using information already available in the dental office. The purpose of screening is to identify individuals who are likely to benefit from treatment. The fact that dental radiographs are regularly made on a large fraction of the adult population makes their potential use as a marker of skeletal health an exciting avenue of research. The purpose of this article was to review the use of various intraoral as well as panoramic radiographs to promote early identification of patients at risk for osteoporosis.

A 37-year-old male patient reported to our department with chief complaint of pain and pus discharge from the labial marginal gingiva in the maxillary right lateral incisor region since last 4 months. Clinically, the tooth was hypersensitive to percussion and palpation but failed to respond to pulp sensitivity testing. After periodontal probing, a palatal groove was observed which started at the cingulum and travelled apically and laterally, associated with a pocket depth of 8 mm. Occlusal radiograph showed circumscribed radiolucency measuring 5 mm×7 mm in diameter at the apex of the tooth. A clinical diagnosis of chronic apical abscess was established. The case was treated with a combination of mineral trioxide aggregate and bone graft. At the 6-month follow-up visit, the tooth showed progressive healing without sinus track and sulcular bleeding.

Alcohol exposure alters oral mucosa. Patient compliance with mouthwash use may be reduced by oral pain resulting from rinsing with alcohol-containing mouthwash. However, information regarding the effects of alcohol consumption and mouthwash alcohol concentration on oral pain is limited. In this double-blind, randomized, controlled cross-over study, we investigated the effects of alcohol consumption status and mouthwash alcohol concentration on response to and perception of oral pain induced by alcohol-containing mouthwash. Fifty healthy men aged 33 to 56 years were enrolled and classified as drinkers and nondrinkers according to self-reported alcohol consumption. All subjects rinsed with two commercially available mouthwash products (which contained high and low concentrations of alcohol) and a negative control, in randomized order. Time of onset of oral pain, time of cessation of oral pain (after mouthwash expectoration), and pain duration were recorded, and oral pain intensity was recorded on a verbal rating scale. Drinkers had later oral pain onset and lower pain intensity. High-alcohol mouthwash was associated with earlier pain onset and greater pain intensity. In addition, oral pain cessation was later and pain duration was longer in nondrinkers rinsing with high-alcohol mouthwash. In conclusion, alcohol consumption status and mouthwash alcohol concentration were associated with onset and intensity of oral pain.

To compare the regenerative potential of bone graft used alone and in combination with barrier membrane in noncontained human periodontal infrabony defects. Twelve patients (7 men and 5 women, 30 to 65 years of age) with moderate to severe chronic periodontitis were included in the study. A total of 16 one- or two-walled intraosseous defects were selected and randomly divided for decalcified freeze-dried bone allograft, alone (control group) or in combination with polylactic acid, polyglycolic acid barrier membrane (test group). Pocket probing depth (PPD), clinical attachment level (CAL), radiologic bone fill (RBF), and alveolar height reduction (AHR) were recorded immediately before surgery and after 3 and 6 months postoperatively. The ANOVA and Newman-Keuls post hoc tests were used for statistical analysis. A two-tailed probability value of P < .05 was considered to be statistically significant. For bone graft alone, PPD reduction was 2.00 ± 0.19 mm, CAL gain was 1.38 ± 0.18 mm, and RBF was 0.63 ± 0.26 mm: for the test group, PPD reduction was 2.75 ± 0.37 mm, CAL gain was 1.50 ± 0.27 mm, and RBF was 1.13 ± 0.23 mm. AHR for the control and test groups was 0.38 and 0.37 mm, respectively. These results confirmed nonsignificant clinical and radiologic differences in regenerative outcome with bone graft alone and with guided tissue regeneration in the treatment of noncontained human periodontal infrabony defects.

Oral submucous fibrosis (OSMF) is a chronic, insidious and disabling condition affecting the oral cavity, being especially prevalent in India and South East Asia. However, considering its high prevalence and potential to undergo malignant transformation, OSMF has not been widely investigated with respect to levels of antioxidants, especially beta carotene. In the present study, an attempt was made to analyze serum levels of beta carotene in 45 patients with oral submucous fibrosis and 45 age- and sex-matched controls. The serum beta carotene level was estimated using the Bradley and Hornbeck method. The serum beta carotene level was significantly lower in the patients with oral submucous fibrosis than in the controls. When the values were compared between different disease stages, the maximum reduction of beta carotene was evident for Grade III OSMF, as compared with Grade I and II. From the present results, it is evident that beta carotene plays an important role in the pathogenesis of OSMF, and that its level decreases with disease progression. OSMF patients should be treated with a diet rich in beta carotene to reduce disease severity and progression towards malignancy.
